Air-assisted booms

Self-levelling

Self-levelling blocking system

Variable geometry

To prevent the excessive heating of the oil we recommend supplying the distributor of the sprayer only when the cylinders are being used.

We recommend having qualified personnel do any adjustments.

5.2AIR-ASSISTED BOOMS

These are booms that use air to make the treatment more effective and decrease wind drift.

They are equipped with a fan (normally hydraulic) and an AIR-SLEEVE that transports the airflow along the entire length of the boom.

They come with their own use and maintenance hand- book, enclosed with the machine.

5.3SELF-LEVELING DEVICES

The self-levelling device keeps the boom parallel to the ground to be treated. It works thanks to the effect of gravity in all the models (except TDL). The oscillation can be blocked mechanically (TDE-TDM) or hydraulically (TDI). The Work boom has a self-levelling device with an automatic block based on cables and springs.

The self-levelling device only works on flat ground, for hilly terrain we recommend the version with trim corrector (TDI 2P) or hydraulic LEVELING (TDL), which lets the operator position the boom with an inclination that is suitable for the ground.

To use, check:

a)that the boom has been mounted in the centre, the weight of the boom must be supported equally on the two halves. To check this, free the self- levelling device from the mechanical (or hydraulic) block and by moving the boom make sure it automatically adjusts its position to be parallel to the ground.

b)in the models that have an adjustable connecting rod, by adjusting the same, it is possible to obtain small variations in trim that can be useful on slightly uneven terrain.

c)in the hydraulic versions it is possible to fit a hydraulic cylinder (TDI 2P) instead of the connecting rod that is adjusted by hand.

d)to complete the self-levelling device we recommend the dragging jet-saver protections

e)keep the sliding parts well greased.

5.3.1 VARIABLE GEOMETRY

Some models of hydraulic boom are equipped with a variable geometry system of the side arms for independent inclination, this system can be used as an alternative to the trim correction or combined with the same.

The angle of the arms is controlled by the operator with electrohydraulic controls.
